Abstract

A pump driver, a disposable pump cartridge for use with the pump driver and a beverage dispenser employing the pump drive are disclosed. The disposable pump cartridge comprises at least one barrel (20) having an inlet valve (24) and an outlet valve (26) associated therewith. A piston (28) movable within the barrel (20) is retained in a minimum volume position during transit by a protrusion (22) on the internal surface of the barrel (20). The piston (20) has a piston shaft (28) with a hollow end arranged, in use, to releasably engage a piston driver to drive the piston (28) from its minimum volume position to an operative position, and to reciprocate the piston (28) within the barrel (20) in its operative position to draw fluid into and pump fluid from the barrel (20) via the inlet valve (24) and outlet valve (26) respectively. Methods of engaging, disengaging and changing the disposable pump cartridge are also disclosed.
